- spring-framework to 6.0.21
- spring-integration-aws to 3.0.2
- spring-cloud to 2022.0.5
- spring-cloud-aws to 3.0.2
- spring-kafka to 6.0.21

The AwsS3ConsumerTests are also adjusted as they broke with the

* Add script to delete all apps

This adds a convenience script that deletes all of
the generated /apps directories. Useful for local
development.

* Update to apps plugin 1.0.14

The previous apps plugin 1.0.10 seeds the apps with Maven
3.5.6 which has issues w/ the current install plugin.

The 1.0.14 plugin seeds the apps with Maven 3.8.8 which
works well.

* Update SCS and java-cfenv versions (2022.0.x)

This updates the SCS starter to v4.0.5 and java-cfenv-boot
version to v3.2.0 to properly support Boot 3.1.x.
